Background: The menisci are considered main elements for a perfect articulation among the articular surfaces. Injuries to the menisci usually occur during weight bearing, and frequently involve a twisting or pivoting motion. The study was to determine the peripheral border length, inner border length, thickness, width and distance among anterior and posterior horn of the adult menisci. A total of 104 menisci from 52 formalin fixed knee joints were utilized for the study at Anatomy department, SMIMS, Sikkim. The peripheral border length and inner border length of medial meniscus was 84.27 ± 7.34mm and 53.98 ± 4.51mm significantly more than lateral meniscus 75.41 ± 6.28mm and 40.19 ± 4.62. A difference statistically significant was observed among the anterior, middle, and posterior thirds of lateral meniscus in which middle thirds was thickest (5.15 ± 0.75mm) (p<0.05) than anterior thirds (3.81 ± 0.688mm) and posterior thirds (4.97 ± 0.827mm) (p< 0.05).The individual analysis of each meniscus showed that the posterior thirds (12.25 ± 2.22mm) was the widest part of medial meniscus (p< 0.05) than the anterior (6.76 ± 0.942mm) and middle thirds (6.63 ± 0.969). In the lateral meniscus the posterior third (9.26 ± 1.42mm) part was the widest (P< 0.05) compared to anterior third (8.89 ± 1.73mm) and middle third (9.2 ± 1.53mm). Conclusion:. The result of this study showed that there is an important relationship between the morphometric data of the menisci. Hence, this study is not only important for orthopedic surgeons, but also for morphologists and embryologist.
